Shsman, you seem very qualified, but have some fun. My quote isn't actually a quote from me, but from one of my dean's, when I asked her why some kids, seemingly so dumb, can get in. I actually go to a very highly ranked school, both academically and athletically. But this goes on at every university, especially the presitgious private schools. They set aside almost 25 percent of their incoming class to the progeny of established alumni, celebrities, and politicans and to varsity athletes.
Yes this isn't fair but neither is life. I am sure you are very qualified but sometimes, it almost seems like a crap shoot on whether you get in to a school or not. I was fortunate to get in to my first choice but many of my friends, who had better grades, test scores, and extras, did not get in.
Shsman, if you really want to get in to a top tier school, stand out. How? I don't know. IntelSTS is great but you have to win at it and each year, more and more people apply and each year's application pool is richer than the previous. Playing tennis helps, but if you just "play" instead of devoting huge hours to traveling across America as a top ranked junior player, it is just a dent to the officer compared to a permanent check mark ingrained in his brain.
Being a master of one thing is a lot better than being a jack of all trades when it comes down to this whole application thing. Fortunately for me, my "one thing" was good enough to stand out.
Also about Newk's, which I have attended, it is a good academy, but the summer coaches just won't make you do as much. Few kids that go there in the summer are superserious about their game, but rather look for a relaxed atmosphere while maintaining their level. and the food is bad.. really bad
